Regulating Crystallization in Wide-Bandgap Perovskite with Removable Additives for an Expanded Processing Window Contributes to Efficient Tandem Solar Cells

Perovskite solar cells (PSCs) have demonstrated significant potential in next-generation photovoltaics, with perovskite-organic tandem solar cells (TSCs) showing promise in surpassing the Shockley-Queisser limit of single-junction devices. However, achieving high-quality...
